You can create a free scalping EA here, but it will not be complete... just working. mql5 website has many but if good will cost to purchase. Your best bet is to decide on a strategy, create, test, test... then you may get a working EA.

i made one for mt4 and mt5 but it says the same thing for both.

@Adisa222 there are a page wich you can make your indicators for free, is another builder. Look on the web for it, is easier to find it

This is the second thread you created for the same question. I replied to the first one. Please don't duplicate threads.

That is a weird strategy or at least I cannot see the market logic behind it. If I understand it correctly, There will be just one open trade at any time (never more than one) moving from chart to chart in a fixed specific order to be open. Are they maybe correlated markets or the opposite? Sorry to ask but I simply don't see how it can work.

@laudable222 What do you exactly mean by 'second window EA'? Only one EA can be running per chart.
